Any tips on how to kill the Odd little girl after she turns into that monster. She just mows through my whole party slicing and dicing them into little pieces All of my magical weapons say "weapon ineffective" Do I need fire items or what? I would appreciate any help.

Nevermind I figured it out. I just used my fired +2 arrows at her, ran away, and when I got enough distance I fired a couple more off. Any easy place to do this is in the room right below the room where she is at. There is a pool there and I just kept going around in circles with her chasing me and firing off arrows. Not the best of tactics but it worked. Another thing is I animated dead a couple of times and let her go to town on them while my mage fired off a couple of Alganazor scorcheres (or whatever the name is)and worked her down. Then I did the arrow thing. Hope this helps anyone that is stuck there like I was
